To allwhom it may concern:

Be it known that I, CHARLES H. Fos'rnn, a citizen of the United States, residing at New York, in the county of New York, State of New York, have inigen'ted certain new and useful Im rovements in Apparatus for Delivering Filled Bags to Sewing Mechanism, of which the following is a description, reference being had to'the accompanying drawing and to the letters and figures of reference marked theron.

My invention relates to an im rovement in apparatus for sewing filled sac s, and particularly to mechanism for supporting and delivering the same at proper and uniform speed to the stitch forming mechanism of a sewing apparatus, such as a sewing machine.

In a patent heretofore granted to Lansing Onderdonk, No. 583,388, dated May 25th, 1897, there is shown and described, an arrangement for supporting, feeding and sew ing up the mouths of filled sacks, in which a sewing machine is arranged in a substantially vertical position, so that its needle bar runs horizontally, and the bags are fed at proper's eed with their tops betweenthe presser oot and o posing bed plate, and sewed by the stitc forming mechanism. The sewing machine illustrated herein is the same as that illustrated in said Patent 583,388, which machine proper is shown described and claimed in Patents 547,675 and 547,676, granted October 8th, 1895, and known as the Union Special Cylinder Machine.

The object of the present invention is to provide an apparatus-which shall be comparatively simple, very durable, and effective, for supporting and feeding the filled bags or sacks to the stitch forming mechanism of the machine and then carrying them beyond, where they can be readily removed by the operator, the speed being regulated to the speed of the machine, and the feeding support for the bags being adjustable to accommodate the different sizes of bags.

The invention consists in the various matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of an apparatus embodying my invention; and Fig. 2

is a front view, partly in section. certain of the parts being broken away for the sake of clearness of illustration.

In these drawings, the sewing mechanism" is herein embodied in a sewing machine of the Union Special type, such as illustratedz'in Patents 547,675, and 547,676, above referred to, and is represented by the letter'A. It is attached to a table or su port B, of any suitable construction, the ciinving shaft thereof being arranged vertically, and the goose neck C, overhanging the edge of the table or support, the needle D working in a horizonta plane the parts being of well known construction, they need not be more specifically referred to.

The supporting table is preferably made of T-iron or constructed asshown in Fig. 1, with suitable legs E. On the under side of the table is en ported a counter shaft F, having the usuai cone and band pulleys and clutch mechanism on it, to which power is applied ,to drive the machine, a belt a passing over one of the cone pulleys serving to transmit motion to the belt wheel on the driving shaft of the sewing machine.

A belt 1) runs from a small cone on the under driver, over an idler pulley to a pulley H, on the upright shaft Q journaled in upper and lower bearings G, G; a center screw 7) working in the lower end of the up right shaft Q, to take up the wear. This upright shaft is provided with a worm c, splined upon it, adapted to slide up and down thereon, it being carried up and down on the shaft by the movement of the bracket d, which is sup orted by, and moves up and down with, the racket 6, provided with a long boss on its inner face, in which isjournaled the shaft is upon which is mounted the worm. wheel f meshing with the worm e. The hubs of the belt pulleys g, are fast on the shafts 7c, the conveying and as the upright shaft Q revolves, the worm wheelfwill revolve, and move the conveyer' belt over the pulleys, thus conveying the bags containing sugar, salt, or other material, to the stitch forming mechanlsm of the sewing machine, the connections between th ez common driving mechanism and the driving, shaft of the sewing machine and the prig-lrt shaft Q insuring the proper cooperativej s eed relation of the conveying belt carrier h, and the stitching si -l f la will-d eiselig that as the gooseneck and belt it running over said pulleys, I

headof the machine, carrying the needle mechanism overhang the edge of the table and the shafts 7:, project also beyond the table, that the convey er is outside the framework of the support and this makes a construction exceedingly convenient for the op:

erator.

The bracket 7: upon which the conveying belt pulleys are su ported, and which is preferably adjustab e up and down to accommodate varying sizes of bags, is herein shown as suitably embracing the front legs or standards of the 'su porting'table or framework, and near eac end has attached to it one end of sprocket chains K, K, which pass over sprocket wheels L, L, on opposite ends of the shaft m. Counterweights M, at the lower. ends of the chains serve to aid in the upward movement of the bracket '5, while the pawl n working in the ratchet wheelv 0 on the shaft m holds the bracket which it is adjusted.

. The end of shaft m is formed to receive a crank N, or otherwise adapted to be retatedby hand, so as to raise' or lower the bracket 43, which. carrying the bracket (1, causes the worm wheel 6 to slide up and down on the upright shaft Q, as well as the in the position to 'worm wheel f meshing therewith.

It will be understood that I do not wish tobe limited to the exact details of construcdriving shaft and the sewing mechanism and between the driving shaft and the conveying mechanism, said means including a vertical shaft having a gear rotating therewith, but

slidable thereon and a horizontal shaft havin a gear meshing with said slidable gear, an means for raising and lowering the horizontal shaft and thereby the gear on'the vertical shaft; substantially as described.

2. In an apparatus for feeding and sewing filled sacks, a suitable sup )orting framework, a sewing mechanism thereon, a driving shaft, connections between the driving shaft and the sewing mechanism, a conveying-mechanism for the sacks, including a vertically moving bracket with means. for adjusting it, shafts carried thereby, an endless band trained over said shafts, one of said shafts being provided with a worm wheel, a vertical shaft provided with a verticall movable worm engaging said worm whee whereby in the adjustment of the bracket framework, a sewing mechanism.

and the conveying mechanism, said latter connectionsinclu'cling an upright shaft, and gearing between the same and the conve 'ing mechanism; and means for raising and" owering the conveying mechanism with the gearing, substantially as described. i I I 4.-.-A apparatus for feeding and sewing filled bii gs, including a sewing mechanism, a
